This paper discussed the CAD / CAM technology of the end face cylindrical cam. The processing of end face cylindrical cam which used in textile machinery was analyzed, and the Processing plan was determined. Three-dimensional modeling and NC programming were done by respectively using PRO/E software and CAXA manufacture engineer software, machining accuracy, fixture and other key technical problems in the end face cylinder cam CAD/CAM process were solved. Acceptable product was processed in common three coordinates milling machine, and ultimately used in enterprises, and achieved good results.

Feature Unit

This paper adopts the parameterized designing method of feature assembled and feature unit. For the feature of non-conventional parts, such as welding box and bearer, using the Visual C++ and AutoCAD as soft tools, the system successfully carries out the basic function of feature assembling, the processing of two-dimensional figure, the building of three-dimensional feature, the automatic producing of technical papers, and so on. The integration idea and design methods of this system can be served as the preference to CAD/CAPP integration for other non-conventional parts.

Alzheimer's disease (AD) is a primary cause of dementia in the ageing population affecting more than 35 million people around the globe. Acquisition of information in everyday life requires memorization in complex three-dimensional environments. Emerging ICT (information and computer technology) applications based on virtual reality (VR) environments can lead to a behavior modification as they provide a photorealistic virtual environment (VE). This chapter provides a selective overview of the empirical evidence available along last five years on the use of virtual reality (VR) to promote everyday life skills and cognitive impairment mitigation of AD patients. Virtual reality allows us to identify and treat deficits in memory that are relevant to everyday life yet not detectable with list learning. Articles related to virtual reality have been divided in two categories according to their use: whether for assessment and diagnostic or rehabilitative purposes. Clinical implications were critically discussed. Suggestions for future research and practice will also be provided.

The Impact

Remarkable science curriculum reform is coming about in the United Arab Emirates (UAE), reflecting a remarkable shifting from the previous science curricula. This type of reform has significant suggestions for teachers. There are limited research studies on teachers‘ perception regarding these reforms. This qualitative study aimed to explore the impact of the Next Generation Science Standard, being the latest science education reform in the UAE, on teachers who are involved in implementing reform. The study was carried out in a US curriculum school in Dubai. Semi-structured interviews with 14 science teachers who teach different grade levels (K-12) were conducted along with 6 class observations. The other source of data collection was the NGSS curriculum documents. The findings showed that the obstacles faced by the teachers with the NGSS curriculum reform were that the curriculum involves big innovative ideas within short timelines, teachers‘ inability to shift the classroom towards the desirable outcome, and the shortage of organization and coherence between the school‘s stakeholders. These finding could be utilized to plan for professional development sessions to support the teachers with more ideas and strategies to convey the implementation of the three-dimensional science curriculum. Moreover, this study could help the leaders and policymakers to ensure the readiness of the teachers and the school before any reform implementation.

Resonance Relation

The paper presents a summary of the results obtained by C. J. Cohen and E. C. Hubbard, who established by numerical integration that a resonance relation exists between the orbits of Neptune and Pluto. The problem may be explored further by approximating the motion of Pluto by that of a particle with negligible mass in the three-dimensional (circular) restricted problem. The mass of Pluto and the eccentricity of Neptune's orbit are ignored in this approximation. Significant features of the problem appear to be the presence of two critical arguments and the possibility that the orbit may be related to a periodic orbit of the third kind.
